JOHN E. PREST, OF FALL RIVER, MASSACHUSETTS.

THREAD-GUARD AND TRAVELER-CLEANER FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 269,231, dated December19, 1882.

Application filed July 17, 1882.

To all whom it may concern:

Be it known that I, JOHN E. PREST, of Fall River, in the county ofBristol, of the State of Massachusetts, have invented a new and usefulImprovement in Thread-Guards and Traveler-Gleaners for RingSpinningFrames; and I do hereby declare the same to be described in thefollowing specification and represented in the accompanying drawings, ofwhich- Figure l is a front elevation, and Fig.2 a rear view, of three ofthe spindles and bobbins ot a ring-spinning frame, theirsupportingrails, and the ring-rail, with my invention applied thereto,the nature of it being defined in the claims hereinafter made. Fig. 3 isa transverse section taken between two next adjacent rings of thering-rail, such being so as to showin side elevation one of the threadguards and its sustaining-shank.

The said invention has particular reference to the thread-guards and thetraveler-cleaner, and to their connection with the ring-rail. Theseveral thread-guards are combined with the ring-rail, so as to bemovable vertically therewith, and also so as to be movable backward fromtheir positions directly between the bob bins or their spindles.Furthermore, each thread-guard is constructed in the form of a wedge ora blade having a flanged back, and the shank or part for supporting theblade is curved or bent or arranged so that its lower part or foot maybe directly in rear of one of the two bobbins, between which the headmay be extended. There is also to such shank aprojection to serve as atraveler-cleaner when close up to the path of revolution of one or bothof the travelers of the rings, through which the said two bobbins mayextend.

In the drawings, A AAdenote the spindles, B B B their bobbins, O and Dthe spindle-supporting rails, and E the ring-rail, all of which may beconstructed and applied in any wellknown manner.

At the back of the ring-rail there is sup ported in suitable bearings,12 b, a rod or shaft, a, which is parallel to the railand at a shortdistance from it.- The several thread-guards F are fastened to the saidshaft, it going through their several feet 0, the same being so thatsuch guards shall be movable vertically with and by the ring-rail, andalso be capable of being turned or moved backward from their (No model.)

is'curved, so that, while the head may be immediately between two nextadjacent bobbins, the foot 0 for reception of the sustaining-shaft maybe directly or about so in rear of oneof such bobbins, such being sothat the shank may not be an obstacle to the attendant while cleaningoff that part-ofthe upper surface of the ring-rail which may be betweenthe rings h of the said two bobbins.

The shank of each guard I provide with a traveler-cleaner, '6, extendedfrom it toward one of the rings. The said traveler-cleaners are toserve,while the travelers may be running around upon the races of therings, to intercept and remove from them (the said travelers) anyfilaments that may have lodged on or been taken up by or caught uponthem.

By having the heads of the guards flanged at their backs or wedge-shaped, as shown, the threads extending from the travelers to theyarn-guides are prevented from contact with each other, so that theguards can be made to extend a less distanceabove the ring-rail thanwould be requisite were theguard-heads without the flanges, the objectof having the guards extend above the ring-rail as little as possiblebeing to prevent the guards, in their upward movement, from being forcedagainst the-yarn-' guides or their supporting-rail and damaging orforcing upward'the same. Byhaving the guards combined with and movableby the ring-rail, they, with it, may becounterbalauced, and as it in itsmovement is notas liable to impinge against them as it is when they areotherwise supported, no irregularity in the supporting-shank, curved orbent as described, whereby when the guard is between two next adjacentspindles the shank at its foot will be in or about in rear of one ofsuch spindles, as

'5 set forth.

2. The combination, with the spindles and the ring-rail, of athread-guard, flanged at its upper part or wedge-shaped, and having ashank curved or bent as described, whereby 10 when the guard is betweentwo next adjacent spindles the shank at its foot will be in or;

about in rear of one of such spindles as specified.

3. A thread-guard having a supporting- :5 shank curved or bent asdescribed, in comthe ring-rail, of the thread-guard having a 20traveler-cleaner extending froinits supportingshank, as set forth, andalso having such shank curved or bent as described, whereby when theguard is between two next adjacent spindles the shank at its foot willbe in or aboutin rear 25 of one of such spindles.
